Anti-feedback technology – No ear-piercing screeches near speakers Review: Good product - This is my second time buying this voice amplifier. The first one lasted me two years. I'm a teacher but I have a very soft voice and I got tired of straining it, so this has been a life-saver. I don't like wearing the headset mic because it gives me a headache, so I just hold up the mic when I talk. I tried another brand last year when I thought I lost this amplifier, but I didn't like it as much. I like that you can also connect another device to this via bluetooth, so you can play music. Overall, would highly recommend for the price point. Review: Gute Leistung, sehr praktisch - Dieses kleine, leichte Gerät für den Gürtel ist wirklich erstaunlich. Es verstärkt die Stimme insbesondere in den Höhen und ermöglicht damit, eine mittlere Gruppe auch draußen, bei Umgebungsgeräusch effektiv zu adressieren, deutlich besser, als dies nur mit kräftiger gehobener Stimme möglich wäre. Der Sound ist etwas blechern, aber das stört gar nicht. ## Features - Effective for Teaching - With a 10-watt output power,the portable voice amplifier with wired headset microphone make your voice louder and travel further, helping students listen more clearly and attentively.
